Magnetoresistive random-access memory (MRAM) is a type of non-volatile random-access memory which stores data in magnetic domains.
Developed in the mid-1980s, proponents have argued that magnetoresistive RAM will eventually surpass competing technologies to become a dominant or even universal memory.
Currently, memory technologies in use such as flash RAM and DRAM have practical advantages that have so far kept MRAM in a niche role in the market.
